Be it known that we, THOMAS E. LEWIS, ALBERT J. RAY, and MILEY B.,WnssoN, citi,-

zens'of the United States, residing atQFort Worth, in the county of Tarrant, State of Texas,have invented certain newfand useful- Improvements in Burners for- Crude Oil, of which the following is a specification, reference being had therein to the drawings. Y

This invention relates to a burner for crude oil, and particularly to a construction by means of which a direct or indirect draft may be utilized in the burningofthe oil.

'rheinvenuon has for an object to' provide a structure of casing through which the oil passes'adapted to provide a' direct draft for -vthe burning of the oil therein or anindirect damper device f or controlling said apertures.

Other objects and advantages of the invention will hereinafter appearrin the following description, y andthe y novel yfeatures thereof i will be particularly pointed out in the appended claims.

In the drawings, Figure l is a perspective of one form of the invention with parts of the casing broken away. Fig. 2 is a vertical longitudinal section thereof. Fig. 3 is a detail perspective of the bottom plate. Fig. 4 is a perspectivewith parts broken away, of a modified form ofthe invention. Fig. 5 is a vertical cross-section through Fig. .4. Fig. 6 is a plan of the damper-slide used with the modified form'of the invention, and Fig. 7 is a similar View of the damper-slide used with the structure shown in Figs. land 2.

Like letters of reference indicate like parts throughout the several figures of the drawings.`

The letter A designates a casing which may be of any desired formation-for instance, as

accompanying',

shown in Figs. l and 2, where it is illustrated as of rectangular shape and provided at its upper portion with an opening A', adapted to be ,closed by a pivoted'da'mper or plate B,

mounted `at B upon the side walls of the casing. The lower portion of Vthe casing'is open, and the front wall A? thereofis provided -at its lower portion with a Series o fuopeningsAs. This front wall is adaptedto restupon a bottom plate 0, While the' rear wall Af of fthe casing is extended at a greater length to pass below the' surface of the bottom plate C.

Within the case a flue-wall D is supported plate a partition()s is formed, which serves to direct the oil "received at that end of the plate toward the front thereof, as shown in Fig. 1. .'At the opposite ends ofthe bottom plate'downwardly-projecting flanges C4 extend and are provided with means for slidably retaining the damper-plate E in position. This plateis providedwith openings Ev', adapted toulie beneath the flanged apertures C2 in the bottom plate, and witha solid portion E2, adapted to close the draft-passage between the flue-wall D and the rear wall A4, while the solid body E3 of the plateadjacent to the openings E closes the apertures C2 when the plate-is shifted toopen a draft-passage at the rear of the bottomplate; l

Suitably supported within thecasing-for instance, by lugs D', carried by the fine-wall D-is a conducting-shelf F, Whichmay be of any desired construction,".forthepurpose of feeding the oil from theinlet-pipe F downward to the lower portion of the casing', vwhere the bottom plate O is located, for the purpose of burning the oil. construction of this plate, we have illustrated As showing a desirable v Idd in Fig. 2 a reversible form thereof, in which the platre is provided with a series of flanged apertures F2, and in the position there shown the flanged portions are upon the upper face of the plate. This upper face of the plate is provided with a iange or wall extending about the two sides thereof and one end, the opposite end being adapted to discharge the oil from the plate onto a lower plate. The reverse or under side of the plate shown in Fig. 2 is provided with tianges F4, extending on both sides and both ends of the plate when reversed, so as to confine thereon the oil which falls upon the plate and cause the same to pass through the apertures F2 and to be there commingled with the draft of air through said apertures. It will be obvious that by changing the position or reversingv the plates shown in Fig. 2 the oil may be fed through the apertures onto the lower plate instead of from the lower end of the plate, as shown in said figure. It will be understood that any ordinary and usual means of connecting the several parts together when assembled may be used and that suitable absorbent material may be placed in the space in front of the wall A2 of the casing for absorbing the oil to be burned, and these nonessential details have not been specifically illustrated or described in connection with the invention.

In the modified form of the invention (shown in Figs. 4, 5 and (5) a cylindrical casing G is employed, which is provided at its upper end with a pivoted cover or closure G and at its lower portion with a series of apertures G2, while the lower open end of the casing is adapted to rest upon a bottom plate H, provided with hanged apertures H. Upon the under surface of this bottom plate a draftslide I is suitably mounted to reciprocate, While centrally of the cylinder a draft-flue J extends 'upward and is provided upon its outer face with a spiral or inclined plate K. This flue and the plates carried thereby may be formed in sections, or the plate K may be applied between the flue and casing and independently thereof. The bottom plate H is provided with a central aperture H2, over which the flue-tube J is adapted to rest, while the damper-slide I is provided with a central aperture I', adapted to permit an upward draft through the hue J. This plate is also y provided with apertures I2, adapted to register with the iian ged openings H in the bottom plate H. When the damper-plate is shifted to bring the apertures into alinement, the solid portion I3 thereof closes the lower end of the Iiue J, as shown by dotted section-lines in Fig. 5, while when the flanged openings of the bottom plate are closed the central draft is open, as shown by the full-line sectioning in Fig. 5.

The inclined or spiral plates K are provided with aseries of flanged apertures K for a similar purpose as described in connection with the apertures F2 of the plates F, (shown in Figs. 1 and 2,) while the feed of oil to said plates is through a suitable intake-pipe, as

shown at K2. The spiral plates are the equivalent in function to the inclined plates shown in Figs. l and 2 and produce substantially the saine operation of the invention.

Under some conditions it has been found desirable to close the apertures in the plates, so as to render the same of a substantially solid character, and this is accomplished by any desired means-for instance, a cap or cover adapted to fit over the flange of the aperture, as shown at F5 in Fig. 2 and by dotted lines at K3 in Fig. 5. This cap when applied produces substantially the results of a solid plate, although under ordinary conditions it is desirable to use plates having the flanged apertures, and the iianges to these apertures maybe formed in any desired manner.

In the operation of this class of inventions it has been found that with an open direct draft of air through the burner much of the combustible material is carried off by the draft and in the form of smoke, so that little or no cinder remains, while with an indirect draft much more cinder is deposited upon the plates, as all of the combustible material is consumed, and the cinder remaining is of a hard character. Under this latter condition all the heat is extracted from the fuel and only the unconsumable residue remains. Under these conditions it is desirable to regulate the character of draft for diiferent fuels or characters of oils, so as to thoroughly consume all of the combustible material therein, thus securing the greatest amount of heat and the consequent economy of the fuel consumed. When a direct draft is desired through the burner shown in Fig. 1, the damper-slide is pushed inward to close the flue at the rear of the casing While the pivoted damper B is open at the upper portion thereof, and the slide-damper E permits an upward draft through the flanged apertures C2 in the bottom plate C, which is the desirable condition of parts when starting the burner. The oil is then fed by any suitable means upon the upper plate F and discharged therefrom upon another similar plate supported beneath the same. The number of these plates employed may be altered at will and is entirely dependent upon the character of burner to be constructed and the material to be burned therein. The discharge from the lower plate is at the left of the rib C3 upon the bottom plate C, which causes the oil to flow into the space in front of the Wall A2 of the casing, Where it is ignited, and the continued iiow of oil passes back into the casing through the openings A3 and is ignited about the flanged openings C2 of the bottom plate C. The result of the burning oil is to heat the plate F, thus causing a direct upward draft through the apertures F2 of the plates and the opening A at the upper portion of the casing. Under these conditions the air and oil are thoroughly com mingled by their passage from the plates, so as to be in the best possible condition for burning. If

IOO

. under other conditions to cut off the passage of air through these plates any one or all of the apertures F2 may be closed by means of the caps F5, as shown Fig. 2. It will thus be seen that the flanged apertures upon the plate are essential and important for securing a feed of oil over the plate without passage through the apertures and for providing a feed of air through the plate. It hasfbeen found that in burning the oil the best results are secured at the edges or margins of the plate, and the use of these apertures provide an increased area of this character. When an indirect draft is used, the pivoted slide B is closed and the damper E shifted `to close the apertures C2 of the bottom plate and open the rear iiue, which causes the air to pass beneath the bottom plate upward through the flue, thence over the top of the flue-wall D and downward over and through theplates F to the apertures A3 at the front of the casing, where the oxidized oil or the admixture of oil and -air is ignited and burns at the front of the casing. When the direct upward draft is used, the oil is burned upon all of the plates except when the plates have been raised to such a degree of heat as to convert the oil into vapor or gas before it reaches the plate below. The casing Vas well as the plates become intensely heated and contribute to vaporize the crude oil as it enters the casing. When the indirect downward draft is used, the tendency is to confine the llame to the lower portion of the casing, and the flame is principally confined -to the lower plate and issues from the openings in the casing, so as to heat the sameto a high degree. In theillustration of the invention here given the oil is shown as fed upon lthe upper plate;

but in some applications of the invention,

such as for locomotive-boilers, it is found desirable to feed the crude oil upon a lower plate, so that the products of combustion passing over the upper heated plates will be converted into a clear-burning gas before leaving the casing.

The operation hereinbefore described in connection with Figs. 1 and 2 applies with equal force to the modified form shown in Figs. 4 and 5, wherein a direct draft is secured by raising the cover or closure G,'as shown by dotted lines in Fig. 5, and adjusting the damper-slide I to permit an upward draft through the openings H in the bottom plate, which passes through the apertures upon the spirally-inclined plates K and over said plates, so as to become thoroughly mixed with the oil which is flowing kdownward overl the surface ofthe plates. When the indirect draft is used with this form of the invention, the cover G is-closed and the damper?y plate I shifted to close the apertures H'- and open the cylindrical flue J, (see'dotted lines,

apertures G2, so as to maintain a body of burning oil upon the plate H.

It will be obvious that changes may be made in the details of construction and configuration of the several parts, as it is not intended to confine this invention specifically to either form herein disclosed, as the scope thereof is capable of numerous dierent applications without departing from the spirit of the invention as defined by the appended claims.
